Happy April Fools Everyone! Yeah, I know it's 4 days late, depending on when you read this, and I had planned on posting on the 1st, but I've just been so busy with my exams. Not to mention my excitement at going to see Dylan Moran - What It Is (which was hilarious, btw) But here, it is, finally posted, sorry it's so late! After this, shall be Ianto's.

Also, I've written this, presuming it's after the events of The Twilight Streets and Idris has remembered all about Torchwood again. :)

Enjoy!

Tosh

Tosh glanced briefly at her watch before turning her attention back to the computer screen. It was only 45 minutes until midday, and technically that meant only 45 more minutes for Jack to strike. But knowing Jack, he'd make up his own rules and Tosh had a feeling he'd be aiming for her next.

And sure enough, she was right. Two minutes later the phone at her desk rung, which was weird enough, as it rarely ever did.

"Hello?"

"Hello, is that Ms. Sato?" The faintly familiar male Welsh-accented voice said.

"Yes, who's asking?"

"I'm from the council, Ms. Sato. Just a final notice, reminding you of flat demolition this afternoon at 3."

"I'm sorry?" Tosh was genuinely shocked for about 5 seconds, before realising.

"Yes, your flat demolition. The notice has been up for 6 months now."

"I'm sure it has." Tosh said, with a smile and glanced a look over towards Jack's office, where he was looking extremely busy with some paperwork. Tosh, however, knew he was listening.

"Yes, it has. I do hope you have removed all of you belongings."

Tosh nearly let out a laugh. She knew the voice sounded familiar. "Idris Hopper, am I right."

"Uh... I'm sorry?"

"I know you are. Idris Hopper. Works for the council, used to work as the mayor's assistant before the earthquake. One of Jack's cronies." Tosh rattled off. Is that the best you can do, Jack? She thought to herself.

"Jack who?"

"Don't play stupid with me. Jack Harkness. Captain Jack Harkness. Guy in a military coat. You kissed him once, if I recall."

"He told you that!?" Idris exclaimed.

"Ah ha!" Tosh said, triumphantly. "I knew it. He told you it was an April fool's prank didn't he?"

"Yes, he did. I didn't really think it was his sort of thing, though."

"No, but revenge is his sort of thing." Tosh said.

"Ah." Idris said and Tosh could picture him nodding in understanding. "Well, he's going to have to try harder than that, I think."

"Oh yes." Tosh agreed. There was a slight pause. "Well I'd better let you get back to your work, Idris. Thanks for the chat."

"No problem. Bye!"

"See you!"

Tosh put down the phone and shot a shy smile in Jack's direction, knowing he was looking her way. Her smile telling him that he had to try harder if he was going to prank her.

Jack grimaced and glanced back down at the crossword he was doing, and began thinking again.

* * * * *

Less than five minutes had passed and Jack had suddenly called an emergency meeting in the boardroom. Tosh knew it was just for another opportunity to prank her, but went anyway, just to play along with Jack and anyone else he'd involved.

"What's this about?" Gwen asked Jack, before taking a sip of her fresh coffee Ianto had brought everyone.

"It had better be worth it, I was on a role, with doing those autopsy reports." Owen muttered.

"It won't take long, I promise." Jack said. Tosh notice how he gave a slight not to Gwen as he said this. So he's got the others involved too. Tosh thought. He is really going to have to try a lot harder if he's going to want to get be back.

"Well?" Owen said expectantly in Jack's direction.

Jack had just opened his mouth to speak when Gwen collapsed. Well at least they've got the timing perfect Tosh though, trying to suppress a grin, as Gwen kneeled on the floor, clutching at her heart.

"Gwen?" Owen was suddenly right beside her. Tosh had to admit he looked genuinely worried. Maybe Jack hadn't told him about it.

"My… it's my… heart." She panted to the three men, as they all crouched around her.

"What is it Owen?" Jack said, sounding slightly over worried.

"Don't know. Her heart seems fine." He said with a slight frown.

"God!" Gwen exclaimed. "Ahh… God, it hurts."

"Gwen, lie down for me." Owen said, pressing a stethoscope on her chest. "Her heart is racing, Jack."

"I... I don't know what's going on!" Jack said, spreading his arms wide innocently.

"Well, don't look at me." Ianto spoke up, as Owen looked at him. "I only bring the coffee."

"Tosh, bring me up my medical kit." Owen said, rushed.

Tosh sighed, but decided to play along for the time being and she left the room. She slowly made her way down the stairs to the autopsy room and picked up the surprisingly heavy kit ("Hurry, Tosh!" Owen had shouted at this point.) and headed back, pausing at the door when she heard hushed voices.

It was Gwen. "Did I do okay?"

"Well, she didn't look too convinced to me." Ianto was saying.

"Why were you looking at Tosh when you should have been looking at Gwen, who was having a heart attack?!" Owen retorted.

"Stop it, guys! Tosh'll be back here any minute, so look in pain, Gwen." Jack commanded.

Tosh, still listening just out of view, gave a grin and waited a few more seconds before walking back it, rather calmly considering the apparent situation.

"Here." She muttered, handing the kit to Owen, making no comment on Gwen's condition.

"Thanks, Tosh. You're a star!" Tosh blushed slightly and stepped back and watched as the medic did his work.

"Is she going to be ok?" Jack asked, concerned again.

"Not sure. We'd better get her down to the autopsy room where I can examine her more."

"Alright." Jack nodded.

"Tosh, Ianto. Give a hand, will you."

Tosh stepped forward and supported Gwen's head while the others carried her and Ianto took the medical kit.

"You know." Tosh began casually. "If you're going to prank someone, you really shouldn't talk about it. Especially during said prank, after sending the one being pranked away where she could easily listen at the door."

Jack and Owen nearly dropped Gwen as she opened her eyes in shock and behind them Ianto began to silently laugh.

* * * * *

It was a few minutes later when Tosh and Ianto's laughter had died down and Gwen had stopped glaring at Jack, who was in turn glaring at Owen, that Jack called Tosh into his office.

"Jack?" She asked innocently, glancing around for any early signs of a prank. "What's up?"

"Not much, I'm just... uh... after some advice." he admitted and Tosh could have sworn he blushed slightly.

"Uh... sure." she answered. "What about?"

"It's Ianto." Jack mumbled, keeping his head down.

"Oh?"

"It's just... I... well, it's more he..." he trailed off.

"I won't tell anyone, Jack. You can trust me." Tosh said kindly, all thoughts of pranks gone momentarily from her mind; for once Jack was trying to talk feelings about Ianto.

Jack nodded and gestured for her to sit down. Tosh pulled out the chair opposite the Captain's and was about to sit down, when Jack let out a small snigger, before clasping his hand over his mouth in horror. Tosh immediately stood up again and glared at her boss.

"What do you really want, Jack?" she asked.

"Just sit down." he answered. "Please?"

Tosh frown at him, before turning to look at the chair, on which was an inflated whoopee cushion. The Japanese woman groaned and rolled her eyes.

"Seriously Jack?" she questioned. "A Whoopee cushion?"

Jack shrugged.

"That is so childish, I cannot believe you'd sink to that level." she shook her head and turned to leave.

"I will get you back, Tosh." he mock-warned.

"Well you're certainly going to have to try harder." Tosh said, grinning.

She heard Jack mutter a curse behind her as she headed back to her desk.

"What did Jack want?" Gwen asked.

"He just wanted to prank me." Tosh replied. "Or rather attempt to prank me."

"What did he do?"

"Put a whoopee cushion on a chair and tried to make me sit on it." she said casually.

"Are you serious? He actually sunk to that level?" Gwen raised her eyebrows.

"Yeah." Tosh agreed, before turning back to her computer screen. "Why isn't this mouse working?" she mused out loud.

"Huh?" Gwen looked up again.

"This mouse." Tosh repeated. "It's not working."

"Is it plugged in?"

"Oh, that would be right. I bet there's a sticky note next to the port saying April Fools, too." Tosh muttered, walking around to the back of the CPU to look.

"No. It's fine." Tosh said, with a frown.

"Really?" Gwen sounded surprised.

"Yeah..."

"What you doing, Tosh?" Owen asked, coming up from the autopsy room and seeing Tosh's bottom poking out from underneath her desk.

"Trying to find out why my mouse isn't working." her voice sounded slightly angry.

"Is it plugged in?"

"That's what I'm checking and yes it is." Tosh replied as though it were obvious.

"Maybe the wire has snapped or something." Ianto appeared and suggested.

"It's possible." Gwen added in.

"No, that's fine too." Tosh responded, moving the mouse around violently in an attempt to make it move on the screen.

"You sure the computer hasn't frozen?" Owen asked.

"Owen, I am as close to a genius with computers as you can get. I think I know how to tell if the computer is frozen. The CPU usage is usually over 50% when it's frozen or in the process of freezing. But right now the usage is saying only 5% which is normal, considering the number of program I'm running." Tosh replied forcefully.

"Techno-babble, Tosh. That went straight over my head." Owen replied, causing Tosh to groan in frustration.

"I just don't get why it's not working. It was fine a moment ago, before I was called into Jack's office..." she trailed off, thinking.

"Tosh?" Ianto questioned.

They all watched as she picked up the mouse and turned it over. On the base of it, covering the laser, which controlled its movement, was a piece of paper.

April Fools!

Tosh gave a slight smile and turned towards Jack's office where she knew he would be watching and smiling. She nodded in recognition and congratulations and waited for the rest of the team to ask, and then laugh, with which she would join in.
